Answer 1

Answer:

A. No, there was not much difference in the two dewlap colors.

Explanation:

Anolis is a kind of three-dwelling lizard, a reptile, which Is commonly found in tropics. One of its most studied traits is its dewlap. The dewlap may have several bright colors and may work as a signal to distinguish species. Although Anolis cooki and Anolis cristatellus represent two different species, they have the same dewlap color, as studied by Dr. Manuel Leal, a biologist at the University of Missouri.
